Nowadays many cars comes with built-in blind spot detection indicator at the side mirror.

Me old skool still turn ma head to look.

Modern cars design sucks
Everywhere blind spots
Not practical

subaru pretty good with their design

A mass production of the F1 halo apply to the pillars, which will highly reduce the blindspots.
It should be able bring down the cost if make it happens.

Apart from that,
Those drivers driving vehicles with BLIS BSM, even with the warning, still behave like shit. Give indicator within a second straight away out from the lane, worse even switch lanes with any indication or sign within a second.

Is it good car have the small triangle windows?

Proton anx perodua have?

My honda siti gm6 A pillar constantly blocking my view everytime during cornering. I have to move my body forward and drive like an 80yrs old granny whenever doing cornering. Roundabouts are the worst

yup, I notice that too when I drive, old car before 90s does not have this issue
